PURPOSE:To provide the title compsn. which is excellent in dispersion and solubility in cold water and fluidity during long-term storage, and which comprises, as indispensable ingredients, an org. surfactant, a water-soluble crystalline inorganic salt, a particular sodium silicate, and zeolite. CONSTITUTION:30-50% org. surfactant (a) contg. at least 70wt.% (hereinafter merely '%') anionic surfactant (e.g., straight-chain sodium alkylbenzenesulfonate) is mixed with 2-15% at least one water-soluble crystalline inorganic salt (b) selected from among Na2CO3, Na2SO4, sodium tripolyphosphate, sodium pyrophosphate, and sodium orthophosphate, 10-25% sodium silicate (c) having an SiO2 to Na2O molar ratio of 1 or more, 10-30% zeolite (d), optionally 5-25% water-soluble crystalline alkaline inorganic salt (e), and optional additives (f) such as antire deposition agents, breaching agents, enzymes, fluorescent dyes, and perfumes to prepare the title compsn. having a particle diameter of 40-2,000mu and a bulk density of 0.5/cm<3> or more. |
